I agree that it would look nicer (or more familiar, to a coder) - but I 
guess it mainly comes down to how difficult it is to implement that in 
the evaluator. I mean, _theoretically_ it should not be difficult to 
implement a "look-ahead" if the evaluator finds ":" to find out if the 
next char is also a ":" - but as I said, I only looked briefly at the 
evaluator, so I can't say if it's actually as easy as it sounds.

Well, after checking the existing code of the plugins (and lots of 
editing this email...), that would sound like a very good idea to me, if 
we can get rid of the (somewhat redundant) "parse". Maybe something like 
a "default function", if only the name of a plugin is supplied?

this would make it
xmms('token')
i2c_sensors('token')
proc_stat('token')
proc_stat::disk('token')
proc_stat::cpu('token', 'delay')

Which would look pretty appealing to me. We'd have the best of both 
(especially being able to have functions, that take more than just one 
parameter)

What do you think?
